Another nice thing about paper books is that you can lend them out to your friends when you're finished reading them. This saves a bit of space, plus your friends can just pick them up and read them without worrying about a bunch of BS like whether it's compatible with their e-reader, if the DRM will work, if the publisher will revoke the rights for some reason, etc.

Or give them away, or leave them in a little free library for someone else to enjoy. In my old neighborhood somebody else had similar taste in scifi and (as far as I could tell) we traded Asimov books back and forth through the book box in the park!

I'd love to keep them all forever but (a) I think my house is about maxed out on shelves and (b) a book's potential is wasted on the shelf.
